Question
Once the network diagram is complete, how many activities or milestones will not have both a predecessor and a successor? A. 1 B. 1 in each phase C. As many as necessary D. 2 in the entire network
Solution
The answer is D. 2 in the entire network. In a network diagram, the first activity or milestone (start point) will not have a predecessor and the last activity or milestone (end point) will not have a successor. Therefore, there will be 2 activities or milestones in the entire network that will not have both a predecessor and a successor.
